Opera has released version 10.52 for the Mac. "The new Opera is designed with Mac in mind. This version boasts an improved user interface, Cocoa integration, multi-touch trackpad gestures and Growl support. This, combined with the unprecedented speed from the new JavaScript engine, Carakan, and the new graphic library, Vega, provides a faster and smoother browsing experience. The new Opera also features the latest in Web standards, including leading SVG support and HTML 5 video." Only Linux remains, now.
